swIiveme-smmne WINDOW Application filed December 9, 1929. Serial No.412,844.

This invention relates to new and useful improvements in a windowconstruction.

The inventionhas for an objectthe provision of a construction of theclass men- '5 tioned which is simple, dependable in use and efficient inaction, and which can be manufactured and sold at a reasonable cost.

The invention proposes the arrangement of sashes within a frame so as tobe pivotal to open positions and also vertically movable to openpositions, and in open positions to be loose within the frame so as tobeea'sily manipulated, while in closed positions to be firm in the frameto provide a tight structure 1 thru which winds cannot blow.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to theappended claims in which thevarious novel features ofthe invention are more particularly set forth.

The reference numeral 20 indicates generally a window frame of customarydesign 7 and provided with vertical sides and a horizontal top andbottom. The vertical sides are hollow and are provided at the top withpulleys 21. Cords 22 extend over these pulleys and the ends within thehollow vertical sides of the window frame are attached tocounter-weights 23 while the other ends are attached to window sasheshereinafter fully described. The counterweights are intended tocounterbalance the weights of the sashes. 8 Near the bottom portions ofthe vertical sides, there are removable sections 2 1 providing for thereaching of the counterweights 23 when new cords are provided for thecord 22, such as is necessary when these cords break or become worn out.

The window. frame 20 is provided with inner sash guide strips 25consisting of vertical and horizontal top and bottom arms,

and is also provided with outer sash guide strips '26 also consisting ofvertical and horizontal arms. Between the inner and outer sashguidestrips, spacer strips 27 are provided consisting only of verticalportions; Thesespacer strips are engaged in vertical the frame 20 as maybe seen from an inspection of Fig. 13.

An inner window sash is slidably mounted between the inner sash guidestrips 25 and the spacer strips 27, and consists of a sash frame 28 andslide strips 29 arranged on both sides. An outer sash is slidablymounted between the outer sash guide strips 26 and the spacer strips 27and consists of a sash frame 30 and slide strips 31 on both sides.

Each of the sash frames are pivotally connected at their verticalcenters to the central portion of the slide strips. The pivotal cons.

nection is accomplished as illustrated in details in Figs. 8 and 9 by aplate 32 attached on the sash frameand supporting a screu 33 with a head34. A second plate 35 is at tached upon the slide strip and is formedwith a cylindrical portion 36 in which the head 34 engages. A spring 37is coaxial upon the screw 33 and acts between the head 34 and the baseportion of the plate 35 for forcing the two plates together. One of theplates is formed with a vertical raised portion 38 engageable with avertical recess in the other platefor normally holding the sash framesvertical, that is in line with the slide strips. The sash frames may bepivoted out of line with the strips as may be gathered from aninspection of Fig. 3 and dot and dash lines in Fig. 9. In this pivotedcondition the raised portion and recess disengages temporarily.

A means is provided for latching the sash frames in line with the slidestrips. This means is shown consisting of a. plate 39 movably mounted ina groove 40 in each side of the sash frame and formed with elongatedopenings 41 engaged by pins 42 fixed within the sash frames. A bracket43 is mounted upon each side of the sash frames and pivotally supports ahandle 44 connected with an.

internal arm 45 eccentrically connected with the plate 39. In thevertical position of the handle 44, the plate 39 engages also in agroove 46 formed in each of the slide strips. This may be seen from aninspection of Fig. 10. hen the handle is pivoted downwards as indicatedby dot and dash lines 47, the

plate 39 will be moved so thatthe portion engaged within the groove 46is moved free from the groove permitting a pivoting of the sash framerelative to the slide strips.

Each sash frame is slightly thicker than the slide strips providing aportion at each side of the sash frame and indicated by referencenumeral 48 in Fig. 13 which is extendable over the spacer strip. Thewidth between the sash'gui'des is greater than the width of the slidestrip so that the shades are loose while the window is open. A means isprovided for forcing the sashes against the spacer strips when in aclosed position. This means consists of a bar 49 attached near the topof the inner sash frame at both sides, and near the bottom of the outersash frame and at both sides as may be seen from an inspection of Figs.1 and 2, and these bars are each provided with an enlarged end 50. Foreach of the bars,

a plate 51 is attached upon the guide strips and is formed with a rightangle arched portion 52 arranged for engagement against the enlarged endfor forcing the sashes against the spacer strips 27.

The window frame 20 is slightly wider than the sashes providing spacesas may be seen in Fig. 13 so that the. window sashes are loose while inan open condition. A means is provided for hol-dingthe sashes firm whenin a closed position and consists of a side protuberance 53 formed atthe central portion of each of'the spacer strips and having a. curvedtop and. bottom as may be seen in Fig. 5. In the closed position of thesashes, the extending. portions48 engage againstthe corners of theprotuberance 53, as. seen. in Fig. 13, and firmly hold the sashesagainst sideward play. This arrangement is very advantageous in thatwhen the window is closed, it is substantially weatherproof while when.slightly opened immedately the sashes are loose and may be readilymoved. It should be understood. that by loose ismeant normallymoving-play while by tight is meant extremely fast so as not to:bepractical for moving;

Figs. 15, 16 and 17 illustrate a modified formof pivot for use insteadof the pivot shown in Figs. Sand 9; Thismodified form of pivot isillustrated merely to. bring out that various pivots may be used forconnecting the sash frames with the'slide strips without departing fromthe invention. As illus-' trated in these figures, the pivot consists ofa plate 55- for attachment upon asash frame and provided with aprojecting screw 56. A spring 57 is coaxially mounted upon the screw andacts bet-ween the slide of thescrew and a second plate 58 also mountedupon the screw and urged against the first plate. This sec- ,ond plateshould be attached upon the slide strip. One of the plates is formedwith a plurality of raised elements 59' engageable in recesses 60 formedin the otherplate. These raised elements and recesses are depended uponto normally maintain the sash frame in alignment with the slide strips;at the same time permitting a pivoting of the sash frame relative to thestrip.

In the modified form illustrated in Figs. 18 and 19, a spacer strip 27has been illustrated provided with acentral section 61 hinged at 62 andlatched at 63. This provides a continuous spacer strip and also per mitsthe latch to be disengaged so that the section 61 may be hingedoutwardly. The section 61 is provided with a protuberance 53' having achannel plate 64 loosely mounted on its side. This channel plate has acentral boss 65 rotatively supporting a screw 66. This screw threadedlyengages in the spacer strip and extends into a recess 67 formed in therear portion of the strip. A nut 68 engages upon the screw for lookingit in adjusted position. Pegs 69 project from the channel plate andengage in apertures formed in the spacer strip so that the screw 66 maybe rotated for extending the channel plate relative to the spacer strip,and the pegs hold the channel strip against pivoting.

The inner and outer sash guide strips 25, 26 may be removed and thesashes also removed so that the section 61 may be pivoted outwards. Thenthe nut 68 is reachable and may be loosened for permitting a rotation ofthe screw 66 and an adjustment of the channel plate. This channel plateacts against the portions 48 of the window sashes and when parts becomeworn and looseness sets in, the adjustable feature may be takenadvantage of for slightly moving the channel plate further out and againproviding a firm construction.

In operation, the window sashes may be raised or lowered as a customarywindow. In addition, they may be pivoted to open positions. When incompletely closed positions as illustrated in Fig. 2,. the sashes arefirmly forced against the spacer strips and insure a weatherproofwindow.

While we have shown and described the preferred embodiment of ourinvention, it is to be understood that we do not limit ourselves to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
